'panel' is local to your __init__ function, so it's not available elsewhere. You should store it as an instance attribute instead : # in __init__: self.panel = wx.Panel(self) # in OnBrowse self.panel.database.SetLabel(patrh) note that unlike some other languages, panel and self.panel are two distinct variables, so you should replace _all_ references to panel by self.panel. -- Cédric Lucantis -- http://mail.python.org/mailman/listinfo/python-list
